Theorem-cerused is a minimalist design created by USA-based designer DAMM. Theorem is an LED desk lamp inspired by the hypotenuse of a right triangle. Bonus points if you can recall from your school days what Pythagoras had to say about this special side. Hand turned solid Ash base, cerused, with a natural beeswax finish. The solid brass neck is hand formed then hand finished by blackening using a natural chemical reaction. A solid brass, hand spun paraboloid shade is blackened as well then fitted to the neck.
